Find the complement of set of U=(1,2,,3,4,5,6,7,8,9,10,11,12) A=(1,2,9) B=(1,6,8,10) C= (1,5,7,9)

Answer 1

To find the complement of a set, we consider the elements that are not in the set.

The complement of set A is denoted as A' and includes all the elements in the universal set U that are not in A.

A' = {3, 4, 5, 6, 7, 8, 10, 11, 12}

Similarly, the complement of set B, B', includes all the elements in the universal set U that are not in B.

B' = {2, 3, 4, 5, 7, 9, 11, 12}

The complement of set C, C', includes all the elements in the universal set U that are not in C.

C' = {2, 3, 4, 6, 8, 10, 11, 12}
